Can we compare a physicist sometime with an ox?

There is a folk story in which two character are main. The two non-human characters young ox and old ox play role in the story. According to the story young ox shows his energy at first and then tired. But the reverse happens for an old ox. The old ox after returning from the field speaks loudly but young speaks slowly. This is just a story. But in an interesting experiment of the law called 'second law of motion' in a research center of Kathmandu, Nepal, the story of the young ox and old ox was compared, if you want to know about it, you can see at: http://aboutprc.blogspot.com/2013/09/experiment-took-day-and-night-all.html
